JRJ I have not tried this, but if you're running 2.4.3 (server and client)
JRJ and don't have an excessive number of exclusions, you can set up a
JRJ dummy dumptype with the information, then inherit it into each real
JRJ dumptype as needed:
JRJ
JRJ define dumptype exclude-stuff {
JRJ exclude file append pattern1
JRJ exclude file append pattern2
JRJ exclude file append pattern3
JRJ exclude file append pattern4
JRJ }
[SKIP]
JRJ And so on. You can, of course, have more than one fake dumptype with
JRJ different sets of exclude patterns. And, since append is used, you
JRJ may reference more than one in a real dumptype -- the entries will be
JRJ merged into a single large list.

JRJ As I said, I haven't even faintly tried this. It's just an idea based
JRJ on how I'm pretty sure this all works.
Looks like exactly what I need :) Thanks. I will try it and see if
it'll actually work. Looks OK to me, though :)

LTO internal vs external labels
Hello there, Wanted to say thank you, with much help we are now running two StorEdge 9 Jukeboxes with LTO drives (one drive per jukebox) with two Amanda configurations on the same host, one for the local client and one for remote clients. Now I have only more more question... The barcode labels, are they actually used to speed locating which tape is which in the jukebox ? If not, maybe I'll replace the labels with something more standard to our site NEWTONLnn, NEWTONRnn (local/remote, left/right drive, your choice). If the barcode labels are, or will be, used, then we need to find a way to also apply a more meaningful (in terms of our site) label to the outside of the tape. We are a little reluctant to stick extra labels on the tapes, its not recommended by the vendor. I'd though of creating new barcodes that match our naming scheme, but don't know how to accomplish that. What experiences/solutions have other amanda_users come across ? thanks, Brian --- Brian R Cuttler [EMAIL PROTECTED] Computer Systems Support(v) 518 486-1697 Wadsworth Center(f) 518 473-6384 NYS Department of HealthHelp Desk 518 473-0773

Rather, I was getting a timeout error from tar, and couldn't track down what file was causing it. So rather than lose the whole partition each time as the tar failed, I split it into 80 little filesystems, and now each one gets backed up independently, except, of course, for the one which is causing the error.

Weekly archive, RAIT ?
Givens: Solaris 8, StorEdge 9 (HP C7145) jukebox - with LTO drive Amanda 2.4.2p2. We are considering running, well, have already configured, two separate amanda servers, one to access jukebox A and service the single amanda-client which resides on the amanda-server machine and a second amands-server to service amands-clients that are _not_ on the amanda-server machine. We are considering leaving most of the tapes in the jukeboxes alone week to week. Providing ready access to one week's data. We are thinking of using the remaining slots in the jukebox for weekly archive tapes. I couldn't think of a good way to mechanistically implement this until I realized that I could have a 3rd amanda-server. This would run on the weekend when the other 2 amanda-servers where quiesent. It would back up the combined disklists of the 1st 2 servers but to an alternate tape pool. Ideally I could install amanda 2.4.3 and have 2 tapes in each jukebox, 4 tapes in all, to write the output to. Am I making any sense ? I'd thought someone said last week that I couldn't walk by amanda run from one jukebox to the other. Anyone have any ideas ? It just seems potentially inefficient to break my partitions arbitrarilly across two different configs. thanks, Brian --- Brian R Cuttler [EMAIL PROTECTED] Computer Systems Support(v) 518 486-1697 Wadsworth Center(f) 518 473-6384 NYS Department of HealthHelp Desk 518 473-0773

Quantum SDLT 320 tape drive.
Hello. I've used Amanda in the past, and I'm going to migrate my current backup system to Amanda. My questions are really about Quantum SDLT tapes and Amanda configuration. I've got about 220 or so GB which need weekly full dumps performed, and nightly incremental. I am planning on using a Quantum SDLT 320 tape drive in conjunction w/ a large hard disk (approx 200 GB). The HD will serve as storage for the incremental runs in this case. Our current setup is a single DSS-4 tape, which was fine about a year ago, but the drive space has grown rapidly while the backup capacity hasn't. My questions are as follows: 1) Is there a way to specify incremental runs to dump to the holding disk as opposed to the tape within the config files? I could just not change the tape until the weekly full dump is scheduled and turn on the auto-flush, but I'm not sure if this is the best way to do things. Running Amanda with a large tape size means consolidating incremental dumps to be flushed at the time of the full run, otherwise I waste a huge amount of tape space. 2) Has anyone used the SDLT 320 drives w/ Amanda? I searched the group archives and didn't get much from them on these drives, same with the FAQ (tape-info would be nice for these drives). 3) I am planning on using a Linux box (running RedHat 8.0) with sufficient power to do software compression. Im wondering if this configuration makes sense for the size / time restrictions on the running of full and incremental backups. Just bouncing the idea off of the group to see if there's any issues involved with this setup. Thanks for your time. __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

Re: NO_AMANDA (was Re: RAIT in 2.4.3b4)
one more thing I'm curious about: is the backwards C idiom if (0 != sometestfunc()) instead of the usual if (sometestfunc() != 0) preferred by amanda developers, or Mr. Mengel? It's very strange to read, I've never seen it before :) Well, I can't speak for the other developers but putting the constant on the left is just good C coding practice. It avoids == vs = typographical errors. Put simply: if ( 0 = x ) is a syntax error while if ( x = 0 ) is not; so if you accidentally type = instead of != or ==, you get an error message, instead of unintentionally making an assignment.

On Mon, 27 Jan 2003, Scott Mcdermott wrote:
I'm not talking about multiple writes to the same tape happening at
once. With a single parity tape, all writes to any drive in the set

same drive head used to record parity information. This limits write
speed to all the drives in the data set combined, to that of the single
parity drive.
That would be true, except *every* drive out there
1) buffers writes
2) writes really slowly, relative to the bus speed.
So the fact that you are writing round-robin rather than in parallel
(which you can really only do if you have distinct SCSI bus/fiber
paths to your various drives anyway) doesn't in practice make
much difference.
Read operations can still go in parallel with RAIT4, but the write case
is of course what needs optimizing for a tape backup system.
The RAIT code also does round-robin reads; once again drive buffering
makes it work quite well in practice.
ok, I just read the RAIT code. A few things, which I'm sure you are
already aware of already (and now your comments make a lot of sense):
- it doesn't have any parallelism at all, so it gains no concurrency
advantages; it simply loops among the data set members, does one
write, blocks, does the other, etc then write the parity tape.
The parallelism you get is that the drives buffer before writing; and
write much more slowly than the buffers can be filled.
- it's limited to RAIT4, and additionally:
- it has the divisor limitation you mention due to this code:
data_fds = pr-nfds - 1;
if (0 != len % data_fds) {
errno = EDOM;
rait_debug((stderr, rait_write:returning %d: %s\n,
-1,
strerror(errno)));
return -1;
}
/* each slice gets an even portion */
len = len / data_fds;
(and the rest of the write implementation)
The reason for that was to avoid the overhead of adding a descriptor
and pad bytes to the end of the frames; this is particularly important
when you want it to work with fixed-1k-block drives and the default
amanda blocksizes...
- the #ifdef NO_AMANDA stuff is pretty much exact duplication.
Anyone consider just moving this out into a library instead of
duplicating whole routines in rait-*.c ?
The RAIT code was initially done to be part of a different package
(the Fermi Tape Tools package) and got migrated to amanda, the
idea was to be able to move it back the other way some day.
I guess there isn't any way, then, to employ multiple write heads at
once, without having different sets of backups that use different tape
devices. This sounds like it would be really hard to set up with a
changer.
That's not true at all, which you'll see if you try it...
Effectively enough, though. If no one speaks up about RAIT, it means no
one is using it. And if they are using it in isolation, they may as
well not be using it.
Well, it may just mean no one who is using it happens to be reading
just this minute. I would be interested to know how many folks
are acutally using it, though.
I'm just saying, when considering it for a production deployment,
measuring list response to questions about it is a valid measure of its
maturity, if not an exact one.
Ah, but what attribute of list response do you measure? Initial response

I think, it would be easier to manage exlude list from the central location, rather then manually copy them over to all clients every time a change is introduced. Well, you could always set up passwordess ssh and scp them over at the beginning of your backup script. Or put them on a read-only NFS export... Marc

Hi,
I have seen a number of suggetstions that it is
possible to configure the rait driver to mirror
backups to disk and tape. I have tried
unsuccessfully to get this going for a while now.
Is there anyone out there that has this going that
can post their exact config and procedures?
I am running amanda-2.4.3 on a Sun Solaris server,
with a sigle tape drive - no changer :-( and I want
to duplicate the backups to a local disk (for in
house backups and offsites).
I have successfully configured both backups to tape
and backups to disk separately, but not to both with
the rait driver.
So that means you should have 2 configs, which when diff-ed,
yeild something like:
5c5
tapedev tape:/foo
---
tapedev file:/bar
for suitable values foo and bar.
What you then want is a config, like those two, whose tapedev
line looks like:
tapedev rait:{tape:/foo,file:/bar}

Re: Quantum SDLT 320 tape drive.

I searched the lw group archives and didn't get much from them on these drives, same lw with the FAQ (tape-info would be nice for these drives). I have an SDLT220 drive; it works just fine. The only issue I have is with compression: I do software compression but I can't seem to get the drive to turn off its internal compression properly. This seems to result in erratic tape capacity. This sounds as if that drive type uses a scheme similar to the DDS drives use, wherein the compression state in effect when that tape was first written, is recorded in a hidden header only the drive can access. So when a tape that been compressed before is re-inserted and recognized, even if the dip switch setting is off, it will turn the compression back on in the process of recognizing the tape. For a DDS drive, one must use mt to turn it off, and then force enough data to the drive to cause it to have to flush the buffers to tape. This then will rewrite that hidden header with the compression flag bits turned off, and you should then have an uncompressed tape. To preserve the tape label, do it something like this, commands adjusted for your environment of course. mt -f /dev/device rewind #save the tapes label dd if=/dev/device of=scratch bs=32k mt -f /dev/device rewind # shut the compression off mt -f /dev/device compression off # now force a buffer flush to update the flags dd if=/dev/zero of=/dev/device bs=32k count=10 mt -f /dev/device rewind # restore the tapes label dd if=./scratch of=/dev/device bs=32k mt -f /dev/device rewind One could clean this up and make it work then put this into a script and run it 30 minutes before amdump is fired off. lw 3) I am planning on using a Linux box (running RedHat 8.0) with lw sufficient power to do software compression. Well, I back up a couple of terabytes of disk to a single SDLT220 drive without problems; the dumps can sometimes take six hours or so but they're always finished by the morning. -- Cheers, Gene AMD K6-III@500mhz 320M Athlon1600XP@1400mhz 512M 99.22% setiathome rank, not too shabby for a WV hillbilly

Oh, the horror! ;) Agreed if sent by e-mail, but if it were instead dumped into a web-served directory... Well, IMO it's still unnecessary. Webservers serve out plain text just fine. Sometimes I feel like such a curmudgeon. Agreed. (the first part, not the curmudgeon) But there's a difference between needed features and desired features. HTML formatted reports probably fall into the desired category. That said, web-based Amanda reports could be useful for those who would rather check a central web site than read yet another piece of mail. My first order of business in the day is to open a central console that fires off to MRTG graphs, big brother reports, a call database, etc. Amanda could be another one of those. A good reason to have HTML reports is features, not prettyness. Use the hypertext part of HTML. For example, error messages could be links to doc that explains in detail what the error means, and how to fix it. -- Tom Schutter (mailto:[EMAIL PROTECTED]) Platte River Associates, Inc.
